The effects of emulsions, pigments, conventional fillers, heat-insulation fillers and film thickness on the reflection and heat-insulation properties under infrared lamp are investigated in order to find the best materials for the heat-insulation coatings. It is found that both the titanium dioxide with high refractive index and the diatomite powder with micro pores possess the optimal reflection and heat-insulation properties, calcium carbonate also has sonic heat-insulation effect. However, the filler such as meerschaum, which in theory possesses the effect, has not shown heat-insulation function.

通过研究涂料配方中所用乳液、颜料、常规填料和隔热填料在红外灯下的反射、隔热和保温性能，发现高折射率的二氧化钛和含有微孔的硅藻土具有最佳的反射和隔热保温效果，轻质碳酸钙和重质碳酸钙具有一定的隔热保温作用，而理论上具有隔热保温效果的填料海泡石等并没有预期的效果。

Based on a computing model of floor heating residences, indoor thermal environment and heat distribution under the effect of heat charge/discharge, operation control and solar radiation has been concluded. Concept and formula of equivalent heat supply has been put forward which indicate that actual heat supply will be equal to the sum of design heat supply and equivalent heat supply. Recommend coefficient has been given taken Dalian as an example. Computed according to the new method, design heat supply can be reduced to 37% in cloudy day and 43.3% in sunny day, energy saving effect is very obvious. In Tromb wall solar house, effect of concrete wall on indoor temperature swing and attenuation of temperature wave is very obvious. While the outdoor air-temperature swing exceeds 10℃, indoor air-temperature swing belows 3℃. In the experiment, maximal difference in temperature between inner surface and outer surface of the 300mm wall exceeded 10℃. Heat storage and collector efficiency varies adversely according to solar radiation. Factors such as thickness, material, absorptance of the wall and permeation of the glass cover all have big influence on heat storage and collector efficiency. There exsisted an optimal thickness of the wall, which can make the best of heat storage and collector efficiency. Most of the heat stored in conventional Trombe wall during the daytime has been lost to the outside at night without heat preservation. Heat preservation on the outside surface of the wall has effectively improved heat release performance of the wall at night, heat supply to the room has increased too.

通过建立的地板采暖系统动态热性能分析模型，得出了在蓄放热特性、运行方式和太阳辐射等因素耦合作用下的室内热环境及热量分配比例，提出了等效供热量的概念及计算公式，指出实际所需供热量应等于设计供热量加上等效供热量，并以大连为例，给出了等效供热量的修正系数，以新方法计算，阴天可减少设计供热量37％，晴天最大可以减少设计供热量43.3％，节能效果显著；集热蓄热墙式太阳房中，混凝土蓄热墙的室温均一化效果和对温度波的削减作用非常明显，当室外温度波动最大幅度超过10℃时，室温波幅不超过3℃，实验中300mm厚墙体内外表面温差超过10℃；墙体蓄热效率与集热效率随太阳辐射照度的变化呈相反的变化趋势；墙体厚度、材料、表面吸收率以及盖板透过率等因素对集热和蓄热效率均有较大的影响，存在一个最佳的墙体厚度值，使得墙体集热和蓄热综合性能最优；传统的蓄热墙夜间没有外保温，辐射散热损失很大，研究表明墙体外保温方式明显改善了蓄热墙夜间的散热性能，增加了向室内的供热量。

The method of CFD numerical simulation is employed to replace experimental investigation. Hence, STAR-CD of the commercial software is used to simulate the outer flow field and heat transfer performance of integrated heat sink with heat pipes cooled by airflow. It is found that simulated results agree with experimental results well, which indicates that simulation method is reasonable and reliable. Further, simulated computations for different fin thickness, fin pitches and air velocities are performed to analyze their effects on heat transfer performance of heat sink. Finally, a new optimized structure of integrated heat sink with heat pipes is provided to meet future demands for cooling CPU and its heat transfer is also evaluated. For multi-heat source and higher dissipation power of electronic devices, the integrated heat sink with heat pipes attatched fins stagged in different positions of channels is presented and its flow and temperature fields are also simulated to enhance heat transfer. As a conclusion, all mentioned above are useful for the design of heat sink with excellent efficiency of heat dissipation and further research.
